Smoke Simulation - Not visualized all over the wanted area
I believe you need to increase the volumetrics clipping end distance. It is in the rendering properties (where you choose between Eevee and Cycles) and then in the Volumetrics foldout :

Be aware that the precision of the particles in the simulation may be affected by that setting. If the simulation is taking place far away you can also increase the clip start distance to narrow down the clipping volume.
